I think we'll need to underline these institution links for accessibility? @natalia-fitzgerald

@meissadia
Thanks for sharing the screenshots. This has helped to clarify some additional aspects of changing this to a link that I hadn't yet considered. I agree that ideally we would add an underline for accessibility and link consistency BUT adding the blue color and particularly the underline will affect the design. There's already an underline line (horizontal line) balancing act going on.

Can we pause on this work of making the financial institution name clickable? I need to think through the addition of the underline. And, since this work isn't tied to our sprint goals I'd like to take some time to discuss it with UX.
